^^^em, she's only 19 months.....my 18 month old would have zero idea if I have a conversation about feelings with him Adore Knuffle Bunny but not sure if that is above this age level tbh.

I don't think it's ever too early to talk about feelings. Kimochi feeling dolls are a good tool, but also just clearly explaining what they are feeling, what you are feeling, etc. when strong emotions are in play. "I can tell that you feel sad when kitty doesn't want to play." "Mommy is happy to see you!"

DD has had a grasp of at least happy, sad, mad, sorry, hurt, from when she started putting words together around 18 months. Her playgroup friends seem to have similar awareness give or take a few months and depending on personality/gender.
